Información adicional

The ability to use AS keyword in the SubFields property of a QueryDef is documented as an invalid pattern and is not supported. https://enterprise.arcgis.com/en/sdk/latest/windows/IQueryName_QueryDef.html "//Invalid sub fields //queryDef.SubFields = "max(Parcel.Area) as Max_Area";" and "IQueryDef::Subfields - This must be a comma delimited list of field names or a * to indicate all columns. Column aliases and functions are invalid."

Solución alternativa

Use an alias for IQueryDef.Subfields instead of the original attribute field name. See below for an example (SDE.DynamicProtectiveDevice is replaced with the alias "A")Instead of doing this:

queryDef.SubFields = "SDE.DynamicProtectiveDevice.FEEDERID AS FEEDERID"quesryDef.Tables = "SDE.DynamicProtectiveDevice JOIN SDE.CircuitSource ON SDE.DynamicProtectiveDevice.OBJECTID = SDE.CircuitSource.DYNAMICPROTECTIVEDEVOBJECTID";queryDef.whereClause = "SDE.DynamicProtectiveDevice.ANCILLARYROLE = 1 AND SDE.CircuitSource.DYNAMICPROTECTIVEDEVOBJECTID IS NOT NULL";

Do this:

queryDef.SubFields = "A.FEEDERID AS FEEDERID"quesryDef.Tables = "SDE.DynamicProtectiveDevice AS A JOIN SDE.CircuitSource ON SDE.DynamicProtectiveDevice.OBJECTID = SDE.CircuitSource.DYNAMICPROTECTIVEDEVOBJECTID";queryDef.whereClause = "A.ANCILLARYROLE = 1 AND SDE.CircuitSource.DYNAMICPROTECTIVEDEVOBJECTID IS NOT NULL";

The above modified query works fine on Oracle 11g and Oracle 12c Release 1.
